lowing is a specification.

y, My invention relates to the art of heating buildings and particularly to gas radiators employed in that art.

The principal object of my invention is Ato provide a gas radiator which will also ing it before delivering it to the room.

Another object of the invention is to pro-o v*vide la gas radiator which will set' up and maintain a brisk circulation in the air ot' the room to Vloe heatd? passing this air through the radiator and forcing it strongly toward the ceiling as it leaves the. radiator.

Another object` of the invention is to control'the proportion of outside air to inside air delivered to the intake o the radiator.

Another object is to provide an auxiliary circulation for all the air ahove a certain plane in the room taking foul air from 'the space below this planev using it in the cornbustion chamber'and passing it oii' through the flue, so that this foul air is constantly being Withdrawn.

Another object of the invention is to proi vide a radiator in whichthe heated portions such a radiator is also greatly reduce-d.

Another object of the invention is to provide a safety door which will shutoff the interior of the radiator while the burner is being lighted so that there will be no danger of explosions Within the radlator due to the presence of, explosive mixtures of air and gas therein Another'obiect of 'the invention is to provide a novel forni of flue construction. .Fur-

ther objects and' advantages ivili/` be made eiddent"e hereinafter.

En the drawings which are for'i'llustrative.

In t e form of .the invention illustrated in these drawings a jacket 1.1 is provided, this Jacket having flat sides 12 and 13, flat ends 11i, and a hot air outlet 15 in the extreme to in which a perforated gratin 16 is secure The jacket ll rests on legs 1%. Secured inside ]acket 11 is a combustion box/2() which is rectangular in shape and has its .lower edges flanged .out and secured to the inside of the jacket 11 as shown at 21 in Fig. 2. Sek cured inside the combustion hoX is a draft box 30,7which has its sides bent out and stcured to the inside of the jacket 11 as shown at 31. series of tubes il@ .are each tightly secured in openings formed in the top of the draft herr 30 and'extending through the space between the draft box 30 and the coiny mand 13 of the jacket 11, these inlets being formed at a point slightly above the point 21. A baie plate 42 is secured to the combustion box 20 and extends down in front of a-ue manifold 43. The Hue manifold 43 is Vprovided with an eccentric cap 44 which may be turned thereon and which has a projection 45 eccentrica-Hy located with relation to the oenter oit' the can and of suitable size to receive :t flue pipe 4G. A projection 50 is formed in the side 13 'of the jacketll and atA the ex= treme bottom thereof and a cold air inlet pipe 51 is connected thereto. A due 52 isy formed in a Wall 53 and the cold air inlet pipe 51 pro jects through the 1oase hoard 54 extending to a point outside the building. A. room inlet is provided in the extreme bottom or the jacket 11 and a cold air damper 61 is pivoted at 62 in such aposit-ion that it Wil `entirely shut oli the draft through the cold air inlet pipe 5i or may he dropped down to entirely close the roorn inlet 60, Draft openings are provided in the wall of the draft box 30 30 and project over the draft openings (5:3.

A gas burner 70 of any of the well known types is located in the bottoni of the combustion chamber which formed between the combustion box 2O and the draft box 30,- A Vdoor 71 is formed in the arc of a circle and is'seoured in a casing 72 so that it wil-l close a, front opening 74 andso that it may be raised to simultaneously give access to the 'burner 70 and-close the'throat of the combustion,` chamber between the combustion box' and the draft box 30.

The method of operation of the invention is as follows:

When itis decided to start the radiator,

the door 7l is lifted from the position shown in full lines inFig. 2 and to the position shown in dotted li-nes in that figure. This shuts olf the combustion chamber from the -burner 70 and connects the space around 1the burner 70 with the outer air. The gas may now be tu-rned lon and the burner lighted without danger of an explosion in the bodyl ofthe combustion chamber. As soon as the burner is lighted the door '7l is closed and,

l the-products of combustion and hot gases aol pass upwardly through the space between they combustion box 20 and the draft box 30 pass# ing between and around the tubes 40 and downwardly through the space between the` combustion box and the draft box 30` The balie plate 42 forces the heated gases to pass to the extreme bottom of'thespace between the combustion box 2O and the draft box 30. T-he 'hot gases then pass around the batl'le plate 42 and into the flue manifold 43. The purpose of making the cap 44 eccentric is to allow it to be turned to suit different positions ofthe opening into the Hue 52, thus giving considerable latitude in the cutting of this opening. Air for combustion is supplied through openings 65. The direct draft ofthe radiator vis upwardly through the draft "box 30 into tubes 40 and outwardlythrough 0r any proportion of air may be'delivered through either opening by regulating the position ofthe cold air damper -6l. -Tlie draft control plates 66 tend to cutoff a small proportion of the draft through the draft box 30-and divert it through the openings' In addition to the main circulation caused by the direct, draft through the draft box 30 there is a secondary circulation through the openings 41'and upwardly between the jacket ll and the outer surface of l lthe combustion box Q0. Maximum ventilatino conditions are obtained when the roominet isclosed andcold outside air only is furnished to' the vdirect draft It is advis-l 'ance of'this internal structure.

mesme tlon consists entircly'in areheating and res circulating of the air in the room through the auxiliary inlets 4l.

lt should be noted (hat the jacket ll is formed entirely of flat sheet materialv which may be painted or enameled and which is always cooi due to the circulation of air bctween it and the combustion box. The jacket also serves to cover up the internal structure of the radiator so that no particular attention need be paid to the appearlt should" further be noted that there. are no pocket-s fornied in the interior of the radiator, all of the space being taken up with circulating air, hot spots being thus prevented andhigh efficiency being attained. The baffle plates ($6 are provided to bank the air from the main draft and provide a forced draft to the burner. A
